GOSCH, OF NORTH TONAWANDA, NEW YORK, ASSIGNOR T GREO-DIPT COMPANY, INC, OF NORTH TONAWANDA, NEW YORK, A GORPORATI'QN OF NEW YORK METHOD OF STAINING SHINGLES Application filed January 2, 19.29.

This invention relates to an improved method of staining shingles while the same are packed in bundles.

Shingles as now generally made are thick at their front ends and thin at their rear ends and these are usually packed in bundles for the market in the form of a plurality of superposed layers of shingles, the thin ends of which overlap each other and are fastened together by a binder surrounding the over lapping thin portions of the several layers.

It has been found in practice that dipping of bundles of shingles in a suitable liquid stain is unsatisfactory because the tight en gagement of the shingles on their fiat surfaces prevents the stain from effectively reaching all parts of these surfaces and often results in leaving bald spots on the shingles which have been held tightly together and therefore :0 not reached by the stain.

It is the purpose of this invention to provide a method or process for staining shingles in bundles so that the same are coated over their entire fiat surfaces without leaving any bald spot and to accomplish this expeditious 1y, economically and thoroughly. To that end this invention consists generally in 190s ening the bundles of shingles as they come from the mills. so that the liquid stain can enter between the shingles and coat the entire flat surfaces of the same, and more specifically this loosening is preferably effected by reversing one or both sticks of the binder which holds the shingles of the bundle together.

In its complete aspect this process includes the further steps of pushing the layers of shingles in the bundle inwardly after being loosened so that the shingles of the several layers engage each other over their entire flat surfaces, and thereafter the contracted bundle is dipped in a liquid stain, then the excess qu d sta n rained ther trem, nd then the. shingles are repacked in bundles tor the trade in the form in which they left the mills.

In the accompanying drawings:

it preferably assumes after being stained ready for the market.

Fig. 2 is a similar view showing the sticks of the binder reversed for loosening the contact of the shingles against one another.

Fig. 3 is a side elevation of a bundle of shingles with part of a binder strip broken away showing the several layers of shingles pushed inwardly relatively to each other so that the same engages one another over their entire flat surfaces.

Fig. 4 is a cross section taken on line 4-4:, F ig. 3.

In the following description similar charactors of reference indicate like parts in the several figures of the drawings.

Ordinarily, wooden shingles as now commonly made and used are provided with a thick rear edge 10 and a thin front edge 12, as shown in Figs. 1, 2 and 3. The shingles are usually packed in bundles at the mills preparatory to shipment and each of these bundles, as shown in Fig. 1, comprises a plurality of layers of shingles which are superposed so only that the thin inner ends of the shingles of adjacent layers overlap one another and the outer thick ends of the same engage each other.

The shingles of the bundle are usually held tightly together in this assembled position by a binder consisting of two binder sticks 13. 13 extending across the central parts of the opposite sides of the bundle, and two bindcr strips. 14-, 14 extending across the opposite longitudinal edges of the bundle and each strip being attached to the outer longitudinal sides of the respective ends of the binder sticks by nails 15 or other suitable means.

W sh ngles are thus pa ked in. bunfi es y s y engage ash, other s tig ty, hat whe th same are ipped in a liquid. t n. the atie only seats'ff ctive y these Surfaces which are exp sed While hose fl u fa es of th shingles which eng h ne a ther, and are heref re were, are t e che preperly by he sta n, if a all, e e y e ng' eithe bald or untested sea s n h e Psrtshf he shingl s, q el e a cos (if stain themes which, as sl ght tha the same is not uniform over the entire surface iii and does not harmonize in shade or depth with the properly coated parts of the shingles and therefore produces an unsightly and unfinished appearance.

In order to permit of thus staining the shingles uniformly over the entire flat sides of the same the shingles in the bundle are loosened so that when the same is dipped in a bath of staining liquid the latter can reach all parts of these surfaces and coat the same to an equal extentover the entire area thereof, thereby avoiding different shades or depth coloring in various parts of the shingles and instead obtaining uniform shading or distribution of the coloring. Various means may be employed for thus loosening the shingles in the bundle a suflicient extent to permit proper access of the liquid stain thereto when the bundles are dipped therein. This however, is easily and conveniently ac complished by reversing one or both of the binder sticks of the bundle so that the connection of the strips with these sticks is on the inner longitudinal sides of the latter, instead of on the outer longitudinal side thereof. By thus reversing one or both of these sticks the bundle is loosened in thickness equal to the thickness of either one stick or two sticks, according to whether one or both sticks are reversed thereby permitting the bundle to expand a corresponding extent and enabling the liquid stain to enter between the opposing contacting surfaces of the shingles and coat them uniformly and evenly.

If the bundles of shingles have been packed very tightly it is desirable to reverse both sticks, as shown in Fig. 2, in order to permit the liquid stain to penetrate the requisite extent between the shingles, but if the shingles in the bundles are not packed very tightly sufficientlooseness between the same can be obtained to permit the liquid stain to coat the contacting flat surfaces thereof by reversing only one of the binder sticks.

In order to ensure uniform distribution of the liquid stain over the entire flat surfaces of the shingles after the bundle has been thus loosened it is preferably to contract the length of the bundle by pushing the several superposed layers inwardly relatively to each other to such an extent that the same, while still held comparatively loose by the binder, will engage with each other over the entire area of their fiat surfaces, as shown in Fig. 3.

Upon dipping the bundles of shingles while in this lengthwise contracted condition the liquid stain into which the bundles are dipped, will coat the shingles uniformly over their entire flat surfaces.

The penetration of the liquid stain between the shingles while contacting with each other over their entire flat surfaces is preferably effected by subjecting the liquid stain to pressure. This is practically accomplished by submerging the bundles of shingles in a tank containing bath of the liquid stain and ap plying air pressure to the interior of this tank while the latter is closed, whereby the liquid stain is forced into the spaces or in terstices between the shingles and caused to coat the entire flat surfaces of the same evenly and uniiormly.

After the bundles of shingles have been thus coated or impre nated with liquid stain the same are subjected to a draining operation for removing any excess liquid stain which may adhere thereto and thus avoid applying an unnecessary amount of stain to the shingles and enabling this work to be done economically.

After such draining of the bundles has been accomplished the shingles are again repacked into bundles of the form in which the same left the mill, as shown in Fig. 1, and then dried in any suitable manner preparatory to being shipped to their destination for use in roofing a building or for other purposes.

Shingles stained in this manner do not show streaks across any part of the flat sides thereof, nor is the shade or depth of the color in one part strikingly different from the shade or depth of color in another part thereof, but instead the coloring or staining of the same is uniform over their entire flat surfaces, thereby equalling in quality of finish and appearance shingles which have been dipped or painted, individually. Moreover, dipping of the shingles when bundled in this manner can be effected much more rapidly and at considerably lower cost than has been possible heretofore.

I claim as my invention:

1. The hereindescribed method of staining shingles which comprises packing a bundle of shingles loosely so that the adjacent layers of shingles engage each other over the entire area of their fiat surfaces, then dipping the bundle of shingles thus assembled in a liquid stain, and then repacking the bundle of shingles tightly so that only the inner parts of the several layers of shingles overlap one another.

2. The hercindescribed method of staining shingles which comprises taking a bundle of shingles which has been packed so that the inner ends only of adjacent layers overlap one another, loosening said bundle, and dipping said bundle in a stain while thus loosened.

8. The hereindescribed method of staining shingles which comprises taking a bundle of shingles which has been packed so that the inner ends only of adjacent layers overlap one another, loosening said bundle, dipping said bundle in a stain while thus loosened, and again tightening said bundle after dipping the same in a stain.

4. The hereindescribed method of staining shingles having thin rear ends and thick front ends which comprises taking a bundle of shingles Which has been packed so that the thin ends of adjacent layers of shingles overlap one another, and the overlapping ends of the shingles are held together by a surrounding binder, loosening said binder, and dipping the bundle of shingles in a stain while thus loosened.

5. The hereindescribed method of staining shingles, having thin rear ends and thick front ends, which comprises taking a bundle of shingles which has been packed so that the thin ends of adjacent layers of shingles overlap one another, and the overlapping ends of the shingles are held together by a surrounding binder, loosening said binder, pushing said shingles inwardly so that the same ongage each other over their entire area, and dipping the bundle of shingles in a stain while thus loosened.

6. The hereindescribed method of staining shingles Which comprises taking a bundle of shingles Which has been packed so that the inner ends only of adjacent layers 0verlap one another, loosening said bundle, dippin said bundle in a stain While thus loosene draining the excess stain from the shingles, and repacking said shingles so that the same engage each other tightly.

In testimony whereof I hereby affix my signature.
